    momentum is \[p=mv\] momentum is p. so if one has greater momentum than the other but they are traveling at the same velocity then there's only one other variable that can change.

    I write the momentum of the green ball as below: \[{p_G} = {m_G}{v_0}\] and the momentum of the orange ball: \[{p_O} = {m_O}{v_0}\] where \(m_G,m_O\) are the masses of the two balls respectively, and \(v_0\) is the common speed. Now I take the ration between the two equation above, and I write: \[\frac{{{p_G}}}{{{p_O}}} = \frac{{{m_G}{v_0}}}{{{m_O}{v_0}}} = \frac{{{m_G}}}{{{m_O}}} > 1\] being, by hypothesis \(p_G>p_O\), so its ratio is greater than \( 1\)
